LSC Resonance Tube

Resonance Tube is an exhibit in the Wonder Why exhibition at Liberty Science Center. When I joined LSC the sound had issues of static, popping, and cutting out. Also the knobs would come loose or break as guests would force the potentiometers past their stop points. LSC was curious if the pots could be changed [ ]

LSC Material Table

Material Table is an exhibit in the Skyscraper! Exhibition at Liberty Science Center. When I joined LSC it had issues with video and sound quality, stemming mostly from the wiring in between the server in the IDF room and the exhibit itself. There was also the complicated process of updating the server with new RFID [ ]

DMX Spot Light Controlled By Cap Touch

I recently had the chance to play around with a DMX controlled spot light, the CHAUVET DJ Intimidator Spot LED 350. I was also able to borrow a USB to DMX box, the ENTTEC DMXIS. I was curious if an Arduino could communicate with the DMXIS using a USB Host Shield, and I also like [ ]

Full Color Picture Test in Tobii Partner Window

At the time of this writing, the Tobii Partner Window on the back of I-Series devices is only ever used by Tobii s software and only to show black and white text. The window s main purpose is to mirror the Message Window in Tobii s communication programs. That way people can read what is being typed without [ ]

Kinect Emulating Bluetooth Gamepad Controlling Fire TV Stick

This was a quick experiment I did with using a Kinect as a game controller for other systems. In this setup I wrote a Windows app that detects hand gestures via the Kinect and then sends them to an ESP32 which runs code emulating a Bluetooth gamepad. In the videos below I play 3 different [ ]

Eye Gaze Controlled Wild Thing

Ben is a 3 yr old with GNA01 neurodevelopmental disorder. His mom reached out to us to setup a Fisher Price Wild Thing to work with Ben s Tobii Eye Gaze to give him some independent mobility. You can find out more about Ben and GNA01 here:https://www.facebook.com/groups/BenGNAO1/https://gnao1.org/about/ For this eye gaze setup we decided to see [ ]

Slam Dunk 2.0

The Slam Dunk is a device which brings students with virtually no mobility into competitive wheelchair basketball. Chris Marotta at the Henry Viscardi School built the original version which worked but he was interested in updating it to have a more stable hold on the ball and to use more readily available components. Here s some [ ]

LED Animated Switch Cable

Thinking about sensory rooms, I was imagining that it could look pretty cool if there was a trail of light that zipped from the switch to the device or devices being controlled once the child activates the switch. Then I thought about even bringing that outside of the sensory room, a switch cable that you could use with [ ]

Custom Proportional Power Wheelchair Drive Controls

My past custom drive controls for PWCs were non-proportional, including the ones I produced based on eye-gaze, voice recognition, and winking. Non-proportional is the simplest to implement on a few levels, including the electrical interface to the chair itself. When connecting through the standard 9-pin connector, each direction (forward, reverse, left, right) is activated by [ ]

Motorcycle LED Strips for PWC Lighting

It s not a new idea to use motorcycle lights and LED strips for power wheelchair lighting, but I was really happy with this one I did recently and wanted to show it here. These LED strips can be used alone or in conjunction with headlights and taillights. Here s some pictures with the room lights on, [ ]
